Richard Rider, chairman of San Diego Tax Fighters, said he also could accept a parking charge but cautioned that the city will have to find alternate funding sources if parking revenues come up short.

The parking issue is just one of many that Jacobs and his committee will have to address as public presentations begin next month before the Balboa Park Committee. Some key areas include:

• Traffic: The plan envisions only eastbound traffic across the Cabrillo Bridge. Visitors would have to exit via Presidents Way and Park Boulevard and return on surface streets or freeways to their westside origins.

• Fountain: Under the proposal, the fountain donated by the late Mary Elizabeth North in the 1990s would be moved from the center of the plaza to the Plaza de California outside the San Diego Museum of Man. Mark Johnson of Civitas, who has been hired to develop the Jacobs plan, said the fountain, while called for in the park master plan, is not typical of Spanish-style plazas and was not a feature in the park at the time of the expositions.

• Public art: Jacobs said the plaza might be a suitable place for the sculptures in the San Diego Museum of Art’s sculpture garden. If that takes place, museum board President Tom Gildred, a member of Jacobs’ committee, said the museum could then proceed to build a new wing — something park supporters have supported as long as it is modeled after the 1915 Science of Man Building that was demolished in the 1960s to make way for the museum’s present west wing.

• Future plaza: If the Plaza de Panama becomes pedestrian only, some park activists want to move on to another goal in the park master plan and replace parking at the Pan American Plaza with reconstruction of the fountains and landscaping that existed at the 1935-36 exposition. The new garage would be large enough to compensate for lost parking in this area outside the Starlight Bowl and Air & Space Museum.

Vicki Granowitz, former chairwoman of the Balboa Park Committee, said the review process is as important as the design details.
